I wasn't able to reproduce the issue. As long as I reference the Telerik.Windows.Controls.RibbonView assembly in the application, the ScreenTips are properly set. Please have a look at the attached sample where I tested your scenario and let me know if it works on your side or if I've missed something.

Greetings,
